摘　　要：光泵ＮＨ_３分子远红外激光一条新谱线的发现秦家银，郑兴世，罗锡璋，林贻堃（中山大学无线电电子学系，广州５１０２７５）关键词光泵远红外激光，放大自发辐射，受激拉曼跃迁分类号Ｏ４３３．５４自１９７０年美籍华裔学者张道源等人首先使用ＣＯ。激光泵浦ＣＨ。Ｆ产...By using a grating- tuned pulsed TEA- CO2 laser with 10R (6) line pumped NH3 molecules in a miniature ASE cavity of 0. 20 m in length, when the pumping energy was about 1.1 J and the pressure of NH3 molecular gas was about 0.9 kpa. We discovered a new line with wavelength about 298 μm which may be a stimulated Raman line by aR(o,o) transition.
